An outcome that would demonstrate that a given population has evolved can be the presence of an adaptation.

<h3>What is an adaptation?</h3>

An adaptation is any morphological and/or phenotypic feature aimed at challenging environmental conditions.

Adaptations are, for example, aerodynamic wings in insects that allow them to survive in the low atmosphere.

In conclusion, an outcome that would demonstrate that a given population has evolved can be the presence of an adaptation.

In a recent year, about 22% of Americans 18 years and older are single. What is the probability that in a random sample of 200 A
Pie

Using the normal approximation to the binomial, it is found that there is a 0.0107 = 1.07% probability that more than 30 are single.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
  • The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with \mu = np, \sigma = \sqrt{np(1-p)}.

In this problem, the proportion and the sample size are, respectively, p = 0.22 and n = 200, hence:

\mu = np = 200(0.22) = 44

\sigma = \sqrt{np(1 - p)} = \sqrt{200(0.22)(0.78)} = 5.8583

The probability that more than 30 are single, using continuity correction, is P(X > 30.5), which is <u>1 subtracted by the p-value of Z when X = 30.5</u>, hence:

Z = \frac{X - \mu}{\sigma}

Z = \frac{30.5 - 44}{5.8583}

Z = -2.3

Z = -2.3 has a p-value of 0.0107.

0.0107 = 1.07% probability that more than 30 are single.

LWhat molecule carries the message that is translated into a protein
Goshia [24]

Here, we are asked what molecule carries the message that is translated into a protein.

  • The molecule which carries the message that is translated into a protein is the messenger RNA (mRNA)

RNA - Ribo-nucleic acid.

The type of RNA which are characterized by the containment of the information for translation into a protein are messenger RNA (mRNA) because they convey the information, or message, from the DNA out of the nucleus into the cytoplasm where Translation occurs. Translation, which is the final step in conversion from a gene to a protein, takes place in the cytoplasm.

P.S: Protein synthesis occurs in the cytoplasm.
